The fungal pathogen #Parastagonospora nodorum utilizes necrotrophic effectors (NEs) to cause chlorosis and necrosis on wheat. NE expression is mediated by an assortment of transcription factors (TFs), the most well-characterized of which is PnPf2. Shota Morikawa et al. provide the first domain-level functional characterization of the virulence-regulating TF ortholog Pf2. Results from the study demonstrate the essential role of the middle homology region domain in mediating protein–protein interactions and effector regulation. This study also unveils evidence that suggests that PnCsn6 contributes to pathogenicity and may point to an important signaling pathway that could work in tandem with PnPf2 for fungal pathogenesis: doi.org/10.1094/MPMI-01-26-0… @karchuntan @CallumVerdonk

What if we could watch pathogenesis in real time? Our collab with @tapomoy89, jointly led by Syona @syonaphyceae and Sree @padmanabh97, shows how soil-like 3D regimes reshape our understanding of plant-fungal interactions!

Do we need to reassess how disease resistance ratings on crops are determined? 🤔
Our @theCCDM preprint revealed co-infection of wheat by P. nodorum & P. tritici-repentis breaks down resistance BUT there is a CAVEAT

Faster scaling to larger species sets, phylogenetically resolved orthogroups, reduced RAM usage.
Thanks to @dr_belcher, Yi Liu & Jonathan Holmes who have joined the team, and as ever OrthoFinder's PI @Steve__Kelly!

We show that the corn smut fungus Ustilago maydis hijacks components of the lateral root initiation pathway to induce gall formation in maize leaves.
Big thanks to everyone involved!

Super happy to share this:
A recombinant, interspecific hybrid of two fungal maize pathogens helps us to understand how effector gene regulation determines infection style and tumorigenesis.
Huge congrats to @janinawern and everyone involved!
